A banker explains the whole history of big banks - where they came from, how they got big, and what happened to them. She tells the complete story of The Big Bank Theory. It's remarkably similar to The Big Bang Theory that explains the history of the universe. (The music is "Una Voce Poco Fa" from Rossini's "Barber of Seville".)

This is Act 3 of "The Big Bank Opera", in which stylish bankers in a swanky Wall Street bar explain the explosive rise and fall of big banking and big bankers.
